Whiteboard cleaner

When I have a meeting I like to draw on the whiteboard and take a photo from the board. And of course I add this picture into Zim for documentation :)

I stumbled into this:

whiteboard cleaner

My Zim implementation:

• I installed ImageMagick to c:\Tools\ImageMagick
• Added C:\Tools\ImageMagick\ to PATH
• Created this batch file wbclean.bat

mkdir "%1\tmp_dir"

cd %1
FOR %%A IN ("*.jpg" "*.gif" "*.png") DO (
    copy %%A tmp_dir
)

FOR %%A IN ("*.jpg" "*.gif" "*.png") DO (
    rename "%%A" "orig_%%A"
)

cd "%1\tmp_dir"
FOR %%A IN ("*.jpg" "*.gif" "*.png") DO (
    convert "%%A" -morphology Convolve DoG:15,100,0 -negate -normalize -channel RBG -level 60%%,91%%,0.1 -resize 50%% "%%A"
)
copy *.* %1\*.*
cd %1
del /q /s /f "%1\tmp_dir"
rmdir "%1\tmp_dir"

• Created a custom tool entry
• Name: Convert Images 50%
• Command: C:\Tools\ImageMagick\wbclean.bat %d
